摘要:
A method for connecting personalized devices through a wireless link, a personalized device, and a wireless connection system using the same are provided. In the method, wireless connection information of a plurality of coordinator devices connected to a personalized device through a wireless link up to now is stored and a priority of the coordinator device is decided using the stored connection information. Then, a channel is set to receive connection information, and connection information is received from a coordinator device through the set channel. If the coordinator device transmitting the connection information is the coordinator to connect, the coordinator device is connected. If not, a coordinator device having the next highest priority is decided.
